摘　　要：为了对超宽带动目标进行有效检测,对其回波的特点进行了分析,在此基础上提出了新颖的基于峰值对匹配的积累算法;设计了一套由功率合成的全固态脉冲发射机、超宽带平面喇叭收发天线阵、正交解调采样接收机、主控计算机四大部分组成的冲击体制雷达目标探测系统,介绍了系统的工作原理;该算法应用于实际系统之中,目标回波在距离门中位置保持稳定,并在积累过程中保持原有的形状,幅度随累加次数增加而增大,这表明了该方法的有效性。To detect an UWB moving target in effect, the characteristics of the echo are analyzed, and the novel accumulation algorithm based on the match of peak-pair is presented. The UWB impulse radar target-detection system including a power synthesis solid state pulse source, a UWB planar horn antenna array for transmitting and receiving, a quadrature demodulation receiver and a computer for controlling is brought forward, and its theory is presented. The algorithm is applied to the test system. The results show that the target echo keep stabilization in the range gate, the shape of target echo is the same, and the amplitude augments with the accumulation number. Therefore, the algorithm is effective.
